Social diversity in the neighborhood districts has been the new approach for the challenges resulting from varieties in cities. Social interpreters of this policy are to create neighborhoods where people of different ages, ethnic-racial backgrounds, income, etc. take a place in it. In this regard, many designers by using the concept of different forms of ownership such as housing schemas, different types of constructing and housing etc. have tried to promote it. Due to the less interest that came toward this issue, the knowledge of this mechanism is poor in urban ecology of Iran. The aim of this study is to assess the effects of urban design in promoting the social mixing which is determined with the research of the Abadan community areas. Relevant parameters have been studied with library studies, field visits and by the use of qualitative and quantitative analytical methods. Therefore, after reviewing the relevant concepts, we are going to test hypotheses by the exامینation of case studies, and finally, the influences of urban design criteria are presented.

It is universally agreed concept that education is a corner s tone for socio economic transformation.  Education has been recognized as weapon to fight backwardness, poverty and illiteracy for ages. Experience have shown that all the good benefit of education has been assured only when there is quality education. However, there are visible indicators that education quality has not been s till achieved in the entire world. Particularly, education quality in developing countries is perceived as discouraging. Hence, the sharp decline of education quality is becoming major concern for developing countries like Ethiopia. This is also more serious concern in emerging regions like Gambella regional s tate where mos t people share pas toralism way of life. It is also unders tandable fact that there are locally known spatial and non-spatial factors that affect education quality. Therefore, the main objective of this s tudy was to identify spatial and non-spatial factors that influence educational quality of primary schools in emerging regions. As methodological approach, the s tudy was used descriptive design approach with mix of qualitative and quantitative method. The main data sources were both primary and secondary data. Primary data were collected from spatial and non-spatial data sources. The spatial information was mainly collected from GPS reading, aerial photo and land use plan. Non spatial primary data were collected using interviews and discussions. The perceptions and reflections of key informants (teachers, students, principals and parents) were entertained by using focus group discussion, key informant interview and public hearings. The secondary data sources were collected by means of desk review. As result, the study was found that education quality in the city is weakening. The underlying causes are, low teachers motivation level, high students- teacher ratio, high students- section ratio, lack of instructional materials, lack of infras tructure and facilities. From the spatial perspective, the education institutions are an unevenly dis tributed that students from the central part of the city are more advantageous.
